The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) reported that three weather systems are currently under monitoring as of Monday, Oct. 30.
In its latest weather update, PAGASA noted that the northeast monsoon (amihan) is affecting Northern and Central Luzon.
A Low Pressure Area (LPA), estimated to be 995 km east of Visayas, is also being closely observed.
Weather Specialist Obet Badrina explained that besides the LPA and "amihan," PAGASA is also keeping an eye on the shear line, which is expected to bring rain to parts of Southern Luzon.
“Patuloy yung pag-monitor natin dito sa Low Pressure Area na nasa loob ng Philippine Area of Responsibility (We continue to monitor this Low Pressure Area inside the Philippine Area of Responsibility [PAR]," Badrina said.
“Maliit pa yung tiyansa na maging bagyo pero inaasahan natin na posible itong kumilos dito sa bahagi ng Bisayas at Bicol region itong LPA na ito (The chance of it developing into a typhoon is still small, but we anticipate that this Low Pressure Area may potentially move towards the Visayas and Bicol region),” he explained.
“Pero asahan natin na sa mga susunod na araw ay posibleng magdadala ng mga pag-ulan itong LPA partikular sa bahagi ng Bisayas at Luzon (However, we should expect that in the coming days, this LPA could bring rainfall, particularly to the Visayas and Luzon regions),” he added.
By Nov. 1 and 2 (Wednesday and Thursday), Badrina said that cloudy weather is expected in parts of Metro Manila, Calabarzon, and Mimaropa areas.
24-hour public weather forecast
According to PAGASA's forecast, cloudy skies with scattered rainshowers and thunderstorms may prevail in the Bicol Region and the Eastern Visayas due to the trough of the LPA or shear line.
Cloudy skies with light rains will also be experienced in Batanes, Cagayan, Isabela, and Aurora due to the "amihan."
Partly cloudy to overcast skies with isolated light rains may persist in the Ilocos Region, Cordillera Administrative Region, the remaining parts of Central Luzon, and the rest of Cagayan Valley, still due to the "amihan."
Metro Manila and the rest of the country will experience partly cloudy to overcast skies with isolated rainshowers or thunderstorms due to localized thunderstorms.
PAGASA issued a warning to the public about possible flash floods or landslides due to moderate to occasionally heavy rains and severe thunderstorms.
